Use a shared external source of randomness, like one of the shortwave “numbers stations”, to seed an agreed upon algorithm that simulates shuffling a deck and dispensing the cards. You’re running the same code on the same data, so you could show the cards you had seen after each hand to confirm everyone is in sync.
